Two elements X (atmoic mass 50) and Y (atomic mass 16) combine to form...
Explanation:


  • Let the atomic weight of X be x.

  • Given, the atomic weight of Y is 16.

  • 32% of Y means, the compound has 32 grams of Y out of 100 grams of the compound.

  • So, the mass of X in the compound is 68 grams (100-32).

  • Now, we need to find the ratio of X and Y in the compound.



Solution:


  • Let the compound have x atoms of X and y atoms of Y.

  • From the given data, we have:


    • x atomic weight of X + y atomic weight of Y = 100 grams (total mass of the compound)

    • y atomic weight of Y = 32 grams (32% of the compound is Y)

    • x atomic weight of X = 68 grams (68% of the compound is X)


  • Dividing the second equation by the first equation, we get:


    • y atomic weight of Y / (x atomic weight of X + y atomic weight of Y) = 32 / 100

    • y / (x + y) = 0.32

    • y = 0.32x + 0.32y

    • 0.68y = 0.32x

    • y/x = 0.32/0.68 = 4/17


  • The ratio of X and Y in the compound is 17:4.

  • The formula of the compound can be written as X17Y4.

  • The formula of the compound can be simplified by dividing both X and Y by 4:


    • X17Y4 = X(17/4)Y

    • X(17/4)Y is equivalent to X5Y


  • Therefore, the formula of the compound is XY5.



Answer:

The formula of the compound is XY5.

Similar Verbal Doubts

The original Hellenistic community was idealized, the Greeks own golden dreama community never achieved but only imagined by the Macedonian Alexander, who was possessed of the true faith of all converts to a larger vision. The evolving system of city-states had produced not only unity with a healthy diversity but also narrow rivalries. No Hellenic empire arose, only scores of squabbling cities pursuing bitter feuds born of ancient wrongs and existing ambitions. It was civil strife made possible by isolation from the great armies and ambitions of Asia. Greek history could arguably begin in July of 776 B.C., the First Olympiad, and end with Theodosuss ban on the games in 393 A.D. Before this there had been a long era of two tribes, the Dorians and Ionians, scarcely distinguishable to the alien eye, but distinctly separate in their own eyes until 776. After Theodosus ban most of the Mediterranean world was Greek-like, in fact, but the central core had been rendered impotent by diffusion. During the eventful Greek millennium, the Olympics reflected not the high ideals of Hellenes but rather the mean reality of the times. Its founders had created a monster, games that twisted the strategists aspirations to unity to fit the unpleasant reality of the Hellenistic world. The games not only mirrored the central practices of the Greek world that reformers would deny but also imposed the flaws of that world. Like the atomic theory of the Greek philosophers, the Greek gamers theories were far removed from reality; they were elegant, consistent, logical, and irrelevant.Part religious ritual, part game rite, in the five-day Olympic Games, various athletes coming together under the banner of their cities; winning became paramount, imposing defeat a delight. As Greek society evolved, so, too, did the games, but rarely as a unifying force. Athletes supposedly competing for the laurel of accomplishment in the name of idealism found that dried olive leaves changed to gold. Each local polis (city-stat e) sought not to contribute to the grandeur of Greece, but to achieve its own glory. As in the real world, in the games no Greek could trust another, and each envied rivals victories. The Olympic spirit was not one of communal bliss but bitter lasting competition institutionalized in games.Directions: Read the above paragraph and answer the followingQ.
